DCS And Field Bus Technology In The Application Of Polypropylene Production Research

With the rapid development of social economy, the proportion of petroleum and hemical industry in the national economy growing, but also facing increased competiti on in the international and domestic markets.In order to meet the market further requi rements for production, quality, and production control process of automatic control sy stem of control requirements and control performance, the introduction of new technol ogy- the fieldbus control system is very necessary.The analysis and research the field bus control system and the integration of DCS and FCS control technology, rebuilding and expansion of the original system, saving energy and reducing consumption, impro ve product yield and quality has special practical significance.Through interviews and field survey, this paper systematically collect the defects f or the existence of the polypropylene production using DCS control, DCS control syst em through a large number of literature research and control characteristics of field bu s control, analysis at home and abroad on the status of DCS and field bus system int egration and technical methods, then targeted to choose the project integration solution s, and to design the plant DCS and FCS integrated control system of the network top ology.In this paper, first of all, and analyses the connotation of the fieldbus technology,summarizes the characteristics of foundation fieldbus technology will be used in this p roject(FF) is introduced in detail;And the composition and control of the enterprise n etwork layer and information integration problems are discussed, DCS and FCS integra ted solutions is studied and applied occasion; Secondly, through the analysis of the au tomation system of a polypropylene plant and the project to the specific requirements of the production plant expansion, designed the DCS and FCS integrated solutions, as well as the realization of the integration of control network scheme based on OPC te chnology;According to the polypropylene production process and new expansion device capabilities, to develop a new scheme, and the main instrument, cable selection and i ntroduction, project implementation to provide a reference for later.The content of this thesis research for China’s petroleum and chemical industry in the process modification and expansion of industrial control system, and has a guidin g significance on enterprise network information system building and integration.
